Advanced engine technology improves fuel economy by up to 20% over previous model chainsaws for longer run times.

Ideal for felling, firewood cutting and storm cleanup, this mid-range chainsaw features a low-emission engine that reduces fuel consumption by up to 10% compared to previous models. The new air filtration system requires fewer filter changes and allows for longer run times.

Pre-Separation Air Filtration SystemThis time-saving technology boosts the efficiency of the engine’s filter system, doubling the time between air filter cleanings. Air drawn into the engine is first separated via centrifugal force, ejecting the heavier dirt particles before being routed to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance.

Anti-Vibration System
STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.

Toolless fuel and oil caps with retainersSimply lift the lever and twist the caps to remove or tighten. There‘s no need to use a tool to tighten or loosen.

Side-Access Chain TensionerThe side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw.

Decompression Valve
The decompression valve, also referred to as 'deco' or 'deco valve', vents compression in the cylinder for easier starting. The decompression valve temporarily reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope. It is opened manually and closes automatically as soon as the engine fires.

MS 311 is rated 4.6 out of 5 by 204.

Rated 5 out of 5 by BWS66 from Excellent SawI bought this saw after reading many reviews on the internet and talking to alot of different people. It has very good power and cuts better than any saw I have ever owned or used. The large chain makes quick work of larger trees and will even rip cut when necessary to split extremely large pieces in halves or quarters. I highly recommend this saw to anyone who cuts alot of wood.

Rated 5 out of 5 by CB0000000000000 from Great sawBeen using a 36cc 16" saw for years. Finally ran into a tree it just couldn't seem to make it thru (not enough power, kept bogging down). Went to the local Stihl dealer and picked up a brand new MS 311. WOW! I know it's only 25cc's (or there about), but this thing ate thru a wet and partially rotten/partially petrified cottonwood tree like a hot knife thru butter (sorry about the cliche, BUT IT DID!). Very happy with the purchase and if I only had more trees that needed cutting... I'm having just too much fun with this thing!

Rated 5 out of 5 by bleubob from Incredible machine!My second Stihl chainsaw and I couldn't be happier. My first one was stolen and I tried to sneak by with a cheaper competitor. Big mistake! When I put this MS 311 to work it was incredible; I had forgotten how dependable they were. Don't compromise, get a Stihl

Rated 5 out of 5 by Tex4605 from Product is as strong as its nameI just used this saw i bought a year ago. One blade and three tank refills filled my 18' trailer 3' high. So happy with my purchase I'm looking at buying another. For the size of the saw it was well balance which made cutting wood extremely easy.

Rated 1 out of 5 by jc6770 from This saw has a flawI am usually a fan of Stihl, having owned Stihl saws for the last 30 years. I bought this saw 2 years ago and kept it proper fuel and oil. Last week I started cutting a log and the saw died, something not normal for this saw. I restarted it thinking it was just cold, since I had just started cutting, it then popped and died again. Now there was no compression or spark. I checked decompression valve, it was fine, when I got home I pulled off the muffler and inside of piston was was badly scarred in one place, so a bearing or ring has broke and ruined the cylinder. The saw was not hot and had never ran hot so know not caused by fuel. I have looked online and this is a common problem it seems with this saw. Not sure if I will replace with another Stihl.
